Food preparation machine includes host computer and motor 12, and the outside cover of motor 12 is equipped with the wind channel housing and forms motor element, and motor element sets up in the host computer, the wind channel housing includes two and half shells 31 and sets up at the end cover 32 of half shell downside, two half shells 31 surround the lock and are in motor 12 outside forms the heat dissipation wind channel in inside, end cover 32 connect in half shell 31's bottom, the inside cavity of end cover 32 forms exhaust passage.

The host computer includes motor mount pad 11 and bottom 4 of equipment from top to bottom, motor element is connected with motor mount pad 11, and bottom 4 seals motor mount pad 11. The bottom cover 4 is provided with an air inlet 41 and an air outlet 42, preferably, the number of the air inlets 41 is two, the two air inlets are respectively located at two sides of the bottom cover 4, and the air outlet 42 is located at the rear side of the bottom cover 4.

The two half shells 31 are provided with buckles 311 which are mutually buckled, and are mutually buckled and installed on the outer side of the motor 12, the bottom cover 32 is assembled at the bottom of the motor and the half shells, and preferably, the fan at the bottom of the motor 12 extends into the bottom cover 32. A heat dissipation air duct is formed between the half casing 31 and the motor 12, an air exhaust channel is formed inside the bottom cover 32, preferably, the air exhaust channel includes a vertical section and a horizontal section, the vertical section is communicated with the heat dissipation air duct, the horizontal section is communicated with the air outlet, and the fan is located at the cross connection position of the horizontal section and the vertical section. In the working process, the fan drives the air to flow, so that the air in the host is discharged from the air outlet, at the moment, negative pressure is formed in the host, and then, the external air flows into the host from the air inlet, flows into the heat dissipation air channel from the air channel inlet positioned at the upper end of the air channel cover shell, flows through the motor, flows into the air exhaust channel and is discharged by the fan, and the whole heat dissipation circulation is formed. In the whole process, because the motor component is formed between the air duct housing and the motor, the structure and the size between the motor component and the air duct housing are stable, and the reliability of heat dissipation and noise reduction effects is ensured.

While the invention has been described with reference to specific embodiments thereof, it will be understood by those skilled in the art that the invention is not limited thereto, and may be embodied in many different forms without departing from the spirit and scope of the invention as set forth in the following claims. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
